Abstract
The utility model relates to a structure for preventing cranks of an electric bicycle from rotating. The structure comprises a rotary shaft installed on a bicycle body, wherein the cranks allowing people to tread pedals are arranged at two ends of the rotary shaft. The structure is characterized in that a fixed plate is arranged on the rotary shaft and close to the bicycle body, a top plate is arranged on the rotary shaft and close to the cranks axially and movably in a sleeving mode, a spring is arranged between the fixed plate and the top plate, a bake wire is arranged on the fixed plate and provided with a wire core, and ends of the wire core are connected with the top plate. By means of the structure, rotation of the cranks can be prevented by friction between the top plate and the cranks, riding of the electric bicycle cannot be influenced due to rotation of the cranks, and potential safety hazards are eliminated.
Description
Technical field
The utility model belongs to Electrical Bicycle technical field, particularly relates to a kind of structure of anti-electric bicycle crank transfer.
Background technology
Electrical Bicycle is the current the most widely used vehicle, has the feature of environmental protection, light and fast.In order to make battery-driven car can meet user's different operatings needs, footstep mechanism is generally installed on battery-driven car, footstep mechanism can in the situation that the battery electric quantity deficiency of battery-driven car play a role, the footstep mechanism of battery-driven car comprises the rotating shaft being arranged on battery-driven car car body, the two ends of rotating shaft are provided with crank, stretcher is installed on crank, because of electric bicycle structure complexity, and boosting mechanism is generally installed in the footstep mechanism of Electrical Bicycle, make battery-driven car in the process of utilizing electric energy to drive, crank in footstep mechanism rotates, affect people's Electrical Bicycle of riding, there is potential safety hazard.
Summary of the invention
The utility model provides a kind of simple in structure, easy to use, structure that can be convenient for people to the anti-electric bicycle crank transfer of riding Electrical Bicycle, eliminating safe hidden trouble for solving the technical matters of the easy transfer of electric bicycle crank existing in known technology.
The technical scheme that the utility model is taked for the technical matters existing in solution known technology is: a kind of structure of anti-electric bicycle crank transfer, comprise the rotating shaft being arranged on car body, the two ends of described rotating shaft are provided with the crank for scrunching, it is characterized in that: in described rotating shaft, near car body, adapter plate is installed, in described rotating shaft, close described crank shaft is to movable set top board, between described adapter plate and described top board, spring is installed, on described adapter plate, brake cable is installed, described brake cable has core, and the end of described core is connected with described top board.
The utility model can also adopt following technical measures:
Described top board is that middle part is with porose annular arrangement plate body.
On the face of the corresponding crank of described top board, be connected with rubber pad.
On described crank, corresponding described mounting of roof plate has the pressing plate that can fit with top board.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, design a kind of structure that prevents the crank transfer of Electrical Bicycle, this structure comprises top board and pressing plate, mounting of roof plate is in the rotating shaft of Electrical Bicycle, pressing plate is arranged on crank, by the friction force producing between top board and crank, prevent that crank from rotating, avoid crank transfer to affect Electrical Bicycle and ride, eliminate safe hidden trouble.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, rotating shaft; 2, crank; 3, adapter plate; 4, top board; 5, spring; 6, brake cable; 6-1, core; 7, pressing plate; 8, rubber pad.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of structure of anti-electric bicycle crank transfer, comprises the rotating shaft 1 being arranged on car body, and the two ends of rotating shaft 1 are provided with crank 2, on crank 2, stretcher are installed, for scrunching.In rotating shaft 1, near car body, adapter plate 3 is installed, the close axial movable set top board 4 of crank 2 in rotating shaft 1, be that top board 4 can be movable along the axis of rotating shaft, between adapter plate 3 and top board 4, spring 5 is installed, brake cable 6 is installed on adapter plate 3, brake cable 6 has core 6-1, and the end of core 6-1 is connected with top board 4.Between top board 4 and adapter plate 3 by compression, under crank 2 mode of operations, the core 6-1 of the brake cable 6 on adapter plate 3 pulls top board 4 to spring 5, between top board 4 and pressing plate 3, has gap, and crank 2 rotates smoothly.Electrical Bicycle, by under battery-driven encapsulation, becomes flexible the core 6-1 of brake cable 6, and top board 4 pushes up the handle 2 of buckling, and with this, prevents crank 2 transfers, eliminates safe hidden trouble, and is convenient to people and rides.
In the present embodiment, top board 4 is with porose annular arrangement plate body.On crank 2, corresponding top board 4 is provided with the pressing plate 7 that can fit with top board 4, is connected with rubber pad 8, to increase the friction force between top board 4 and crank 2 on the face of the corresponding crank 2 of top board 4.
